PURPOSE:To perform easily the control of the memory and to shorten the data aligning time by providing two same constituted memories at one comparing unit. CONSTITUTION:A data aligning device 10 is constituted by connecting in cascade plural comparing units 40-I-40-U. Respective comparing units 40 are composed of a memory 103 to store one side aligned data partial set inputted from an input terminal 601, a memory 104 to store the other side aligned data partial set, reading/writing circuits 105-1 and 105-2 to read and write respectively the data to memories 103 and 104, registers 106 and 107 to store respectively one byte of the data of the memories 103 and 104, a comparator 108 to compare the value of the data stored at the registers 106 and 107, a multiplexer 109 to select the channel for transferring the data of either of the registers 106 and 107 to an output terminal 102, and a control circuit 110 to receive the compared result signal from the comparator 108 and to control respective parts of said comparing units based on it. |
